Opening a Company in Switzerland in 2027: The 12-Point Checklist Before You File

Published on October 17, 2026 and written by Cyril Jarnias

Marcos is a foreign founder ready to file. He has a name, a canton and a capital amount. What he does not have is a single document proving the bank will open the account, the form he chose matches his investors, or the canton will treat him as a resident. He files anyway, and loses six weeks.

Opening a Swiss company looks simple — a form, a capital, a register entry. In practice most delays and refusals come from points a founder never checks before filing. This is the working checklist: twelve points that decide whether your incorporation holds, ordered the way they actually bite.

Listen to this guide

The 12 Points, In the Order They Bite

1. Legal form matched to your cap table

GmbH (Sàrl) for a close circle at CHF 20,000 fully paid; AG (SA) at CHF 100,000 nominal with at least CHF 50,000 paid in, when you expect investors or transferable shares. The form is a financing decision before it is an administrative one.

2. Capital actually available and blocked

The capital must exist and sit in a blocked account before registration. Do not count it as a cost — it stays in the company — but do have it ready.

3. A Swiss-resident representative

The company must be representable by a person domiciled in Switzerland with signatory power (art. 718 for the AG, art. 814 for the GmbH). This is a company-law requirement, separate from your own residency.

4. A bank that will actually open the account

This is where most files stall. For a non-resident, expect AMLA/FINMA checks, source-of-funds questions, and possible refusal. Confirm the banking route before you file, not after.

5. Registered office and address substance

A registered office is required. A domiciliation without any economic link is exactly what banks and authorities scrutinise. If you have no premises, plan a clean office solution and understand what it signals.

6. Company name availability

Reserve and check the name before drafting documents. A rejected name reopens the whole file.

7. Canton chosen for the right reason

The canton is where the company is genuinely taxed and where you live, not a brochure rate. Effective corporate rates range from roughly 11.66% to 20.54%, and your personal rate is a separate computation.

8. Accounting and audit obligations

Know what bookkeeping and audit regime applies to your size and form before you start invoicing. The AG audit rules (CO art. 727/727a) do not apply by analogy to the GmbH.

9. VAT position

Standard VAT is 8.1% (reduced 2.6%). Registration depends on turnover thresholds and on whether you sell abroad. Decide voluntary registration deliberately.

10. Withholding tax awareness

Dividends carry a 35% withholding (Verrechnungssteuer) with relief mechanisms depending on the shareholder and treaty. This changes how you plan distributions long before the first dividend.

11. Social insurance and payroll if you hire

Employees mean AHV/AVS contributions, contracts and payroll. A founder employed by their own company enters the same system. Plan it before the first hire.

12. Realistic year-one budget

The advertised package is the paperwork. A company that holds up costs roughly CHF 7,000 to 25,000 out of pocket in year one, plus the blocked capital — not the CHF 1,800–3,500 the first search ads imply.

The Documents That Make or Break the File

Registration itself is quick once the file is complete. What takes time is assembling documents that survive scrutiny. In practice, a founder should prepare:

• Identity and ownership — passports, proof of address, and a clean statement of who ultimately owns the company.
• Source of funds and wealth — where the capital comes from, traced and documented, because the bank will ask before it opens the account.
• The business plan — activity, clients, revenue logic; thin for a simple GmbH, decisive for a third-country permit.
• Corporate documents — articles, the choice of representative, and the registered office solution.
• Translations — official documents must be in Bulgarian for a Bulgarian company, in the local language for a Swiss one; a mistranslated or unvalidated document blocks the filing.

The lesson founders learn late: the bank file and the registration file are not the same document, but they must tell the same story. A capital that appears from nowhere, an address that is only a mailbox, or an owner hidden behind a nominee will stall one file even if the other passes.

What the Numbers Actually Look Like

Item	Indicative range (2027)
State registration fee	small, fixed by the registry tariff
Notary and drafting	part of the setup, varies with form
Blocked capital (GmbH)	CHF 20,000, fully paid — not a cost, stays in the company
Blocked capital (AG)	CHF 100,000 nominal, at least CHF 50,000 paid in
Registered office	recurring annual cost if you have no premises
Accounting and filings	monthly + annual, itemised quote
Bank account	maintenance + possible non-resident compliance cost
Corporate income tax	10% in Bulgaria; in Switzerland, cantonal and federal combined

The single most useful number to remember is not the registration fee. It is the year-one cash you do not get back, and the recurring lines — office, accounting, bank — that decide whether the company is sustainable beyond month three.

Timeline: What Happens in What Order

1. Choose the form and confirm the name.
2. Prepare and validate the documents.
3. Open the blocked capital account and fund it.
4. File with the commercial register; obtain the extract.
5. Convert to the operating account and register for VAT if relevant.
6. Set up accounting and, if you hire, payroll.

Each step depends on the previous one, which is why the checklist order matters. A bank that refuses at step three invalidates a registration done at step four — so confirm the bank before you file, not after.

Where Files Actually Fail

Checkpoint	Favourable	Median	Unfavourable
Bank account	Pre-agreed, non-resident KYC ready	File accepted with extra documents	Refusal after filing
Substance	Real office + activity	Office solution + early clients	Domiciliation only
Form	Matched to investors	GmbH, revisable	AG chosen without need
Timeline	3–4 weeks	6–8 weeks	Months, rework

Read the columns as a planning grid, not a promise. The founder who checks the bank and the substance before filing sits on the left; the one who files first and discovers the bank later sits on the right.

Choosing the Canton (and Why It Is Not Just Tax)

The canton is often treated as a tax line, but it decides three different things at once. It sets the cantonal and communal corporate rate that applies to the company. It sets your personal rate if you live there. And it is the authority that first examines your permit file if you relocate. A founder optimising only the corporate rate can end up with a higher personal bill or a harder immigration file.

Effective corporate rates across cantons run from roughly 11.66% to 20.54%, and the federal layer (about 7.83% effective) is identical everywhere. The entire spread lives in the cantonal and communal layer — which follows where the company is genuinely managed and taxed, not the canton printed on a marketing page. Choose the canton for the substance you can actually demonstrate, then model both the company and personal layers.

The Week Before You File: A Short Final Pass

Most avoidable failures are caught in the last seven days, not in the first month. Before filing, confirm in writing: the bank’s acceptance of your profile and source of funds; the registered office contract and what it signals to authorities; the representative’s signature authority and access to the share register; the exact capital amount and that it is available to block; and the translations, validated, not pending. If any of these is “in progress”, do not file — the register will accept the entry, but the bank and the canton will not be bound by it, and you will redo the work later.

The Recurring Costs People Forget

The registration is a one-off. What sinks budgets is the recurring layer: the registered office if you have no premises, the accountant and annual filings, the bank maintenance and any non-resident compliance, VAT compliance once you register, and the social-insurance and payroll cost if you hire. Get every recurring line quoted in writing before you commit, because these are the costs a founder discovers in month two, not month one.

When Switzerland Is the Wrong Choice

A checklist protects you from mistakes, but it does not tell you whether Switzerland is the right seat at all. Three situations should make you pause before filing:

• You will never operate from Switzerland and have no substance. A company run entirely from abroad is the letterbox case that banks and tax authorities scrutinise first.
• Your only goal is a low headline tax rate. Swiss rates are moderate, not the lowest; a canton brochure figure is not your effective rate, and substance decides the rest.
• You need a residence permit fast. The company does not buy the permit, and a third-country permit can take months and is quota-bound.

If one of these applies, the honest step is to compare seats — Switzerland against an EU member state, against Bulgaria or Ireland — before spending on a registration you may need to undo. The comparison is a page of its own in this cluster, and it is worth reading before the checklist is executed.

The Bottom Line

A Swiss incorporation is not hard once the file is coherent; it is unforgiving when it is not. The twelve points above are not a formality — each one maps to a step where a real file has stalled, and each one is cheaper to check before filing than to fix afterwards. Work the list in order, confirm the bank and the substance first, and the registration becomes the easy part.
